Arthritis in Dogs & Cats

Published on 3 Feb 2021

Arthritis in Dogs & Cats - old dog and cat on couch.

Osteoarthritis or Degenerative Joint Disease, more commonly known as arthritis, is a prevalent orthopaedic disease of dogs and cats. It refers to is a progressive and chronic inflammation of the joints which results in degeneration of the cartilage in the joint. 

Cartilage in the joint deteriorates so that cushioning that once protected the joint is no longer able to do its job. The resultant joint instability encourages the growth of osteophytes, or bone spurs in the joint as the body tries to compensate for the loss of cartilage. This results in pain and stiffness in the joint. 

The joints most affected by arthritis are generally those that work the hardest, such as the knees, elbows, shoulders, and hip joints but any joint can be affected.

Who is affected?

Arthritis can affect any breed or age of dog or cat. It can occur as pets become older or when there has been a past injury, congenital or conformational abnormality. Underlying problems such as hip and elbow dysplasia also cause arthritis. It also develops with natural wear and tear on the joints with age. 

According to PetSure data over the 2020 calendar year, Arthritis was most prevalent in the following breeds of dog:

Dog Breed Prevalence*
Rough Collie5.78%
Shetland Sheepdog4.52%
Golden Retriever 4.23%
Dogue De Bordeaux 4.23%
Great Dane3.75%
Bernese Mountain3.62%
Alaskan Malamute3.44%

*Prevalence = Total number of unique claiming pets / total number of insured pets across 12-month period. Excludes breeds with less than 500 active pet insurance policies.

Over the same period, Arthritis was most prevalent in the following breeds of cat:

Cat Breed Prevalence*
British Shorthair0.62%
Domestic Shorthair0.57%
Russian Blue0.50%
Maine Coon0.29%

Signs of Arthritis

Arthritis in dogs often manifests as lameness or limping on an affected limb/s. Stiffness may also occur on rising. Some dogs may appear stiff or lame after exercise. 

Our feline friends can be harder to read. Some cats may become irritable (or more irritable in some cases!), have issues going to the toilet, or become generally less active. 

Reluctance to jump or head up and downstairs could give you another clue that your dog or cat might have Arthritis. 

Sometimes, swelling in the affected joints may occur. These signs can be indications of pain or discomfort and they can also be symptoms of very serious diseases including osteosarcoma (bone cancer). Don’t delay in seeking out Veterinary advice if you notice changes in your pet. 

Diagnosing Arthritis

Arthritis is typically diagnosed through a combination of understanding the pet patient’s history, including past injuries or surgeries; a thorough clinical examination to identify areas of pain, crepitus (which is the feeling or sound that the friction in the diseased joint makes), or swelling in the pet's joints; and observing the pet walk and move. X-ray or CT (or CAT scan) is also commonly used to help diagnose arthritis as well as check for other conditions such as hip dysplasia, elbow dysplasia, cruciate ligament disease, patella luxation, developmental abnormalities, or tumours. 

Managing Arthritis

Unfortunately, arthritis is not curable, and it is painful. So, pain management is very important in keeping arthritic pets comfortable and happy. Blood tests are commonly performed to check pet’s suitability for long term anti-inflammatory use and repeated periodically to check ongoing suitability. 

Pentosan polysulfate may be recommended in addition to pain relief medication. This drug is used to help stimulate growth of and protect the damaged cartilage. 

Glucosamine or fish oil (omega-3) supplements may also be recommended as part of the management of Arthritis in pets. These may come in the form of powders, chews or included in special diets. Mover & Shaker meal topper for dogs  is also rich in Omega 3 fatty acids from freeze-dried Salmon Powder and v Green Lipped Mussels which help reduce the degradation and inflammation within the joint. It also includes Kale Powder, Rose Hip Powder and Hemp Seeds which provide valuable joint support as they are rich in essential vitamins and amino acids. 

Activity is still important in pets with arthritis, as maintaining muscle mass helps increase stability and reduce pressure on the bones and joints. Weight loss in obese pets is likely to be recommended because excess weight puts extra strain on bones and joints, which can worsen conditions like arthritis. Choose low-impact exercise, such as swimming for dogs. In some situations, surgery may be required such as for cruciate ligament disease, hip, or elbow dysplasia. 

As arthritis needs long term management, regular vet check-ups are necessary.
